Task Manager wont open w/ ctrl alt delete, or shortcut

Trying to bring up the task manager a while back, it would not come up when i pressed ctrl alt delete, i even made a shortcut to it but this time when clicked and error message came up telling me "Another program is currently using this file.". I am running windows xp professional version 2002 service pack 2.
ive used spybot:search and destroy as directed by a colleague, aswell as ad-aware se, and hijack this, both in and out of safe mode trying to correct the problem. i am attaching the logfile i saved from my most recent use of hijack this in safemode. plz, i need help.

I don't need polite (though it helps...).
I want people to get rid of their gremlins.
With today's free AVs available, such as from http://free.grisoft.com, it is gross ignorance, and complete stupidity, to think you don't need such a program.

i dont spend all my time on the computer, and maybe it was a little ignorant and ****ey to think that the protection ive already got w/ my router and other utilitys was enough. i'm downloading the avg you gave me a link to and i appreciate it. i did exactly that with hijack this, i read the way ppl wanted it done the first time around as i said. but just incase you meant you wanted to see another im attaching one.
